  • It could be a case of too much cooling, while simultaneously being too much heat.

    If you’re blowing so much air that the filament instantly solidifies when it leaves the nozzle, it’s not going to bond with anything else. It’s also interesting that the first layers are fine (when the part cooling fan is typically not running), but problems start when the part cooling fan turns on.

    Have you tried without part cooling at all? Another thing is that your part cooling might be cooling down the tip of the nozzle, causing tiny partial clogs, which are cleared every so often by friction.


  • Did you notice a difference in print speed when you slowed down? As this is a small print, it could already be as slow as it will be due to minimum layer times.

    It could also be that the nozzle spends too much close to the print. What happens if you print 2 or 3 of them?

    This is typically more of an issue with PC where you don’t have a part cooling fan running, but maybe it’s the case here too?




  • If the point is to monitor the other divers’ cylinder pressure, I believe there’s only the Garmin transmitters that have sufficient range for that (and even then, it’s tricky). Most transmitters will top out around 1-2m range, whereas the Garmin transmitters can have a range up to 10m (in ideal, line-of-sight conditions). I believe you can have up to 4-5 transmitters paired with a computer.

    I would recommend teaching everyone good habits and have them monitoring their own pressure, but that’s just me.




  • As far as I know the 1DXIII is still being produced, nearly 4 and a half years after its launch.

    Single lens reflexes have one massive advantage: the sensor is not being used while you’re composing or idle, which means the sensor doesn’t heat up as much. Hot sensors generate noise, which you then have to compensate for (by doing an equal exposure with the shutter closed to remove the hot pixels).

    But mirrorless is faster, cheaper to produce, smaller. It’s inevitable that DSLRs will soon be a relic of the past. But they won’t be for a while: 30% of the enthusiast market in 2022 was still DSLRs.
